Abstract

L'invention concerne un procédé et un dispositif d'attribution de ressource permettant d'éviter le gaspillage de ressources. Le procédé d'attribution de ressource comprend les étapes suivantes : un dispositif terminal demande un ordonnancement semi-persistant à un dispositif de réseau; le dispositif terminal reçoit des informations d'attribution transmises par le dispositif de réseau, les informations d'attribution étant utilisées pour attribuer une première ressource d'ordonnancement semi-persistante pour le dispositif terminal; le dispositif terminal attribue la première ressource semi-persistante pour le dispositif terminal en fonction des informations d'attribution; et le dispositif terminal transmet des données de liaison montante au dispositif de réseau sur la première ressource d'ordonnancement semi-persistante.
